didn't just fill our plaza. we filled all the surrounding streets and city blocks. sorry, nypd, it's absolutely huge, and we'll have a concert for the fans who have been waiting since last week in some instances. >> but first breaking news and developments in the scandal that led to the resignation of cia director david petraeus. >> as you might imagine, a lot of players and moving parts to this story, and it's just breaking this morning. we have a quick review. it all began when jill kelley, a florida socialite and married mother of three complained about ma racing e-mails. the fbi said it traced those e-mails to this woman, paula broadwell, a married west point graduate and biographer of david petraeus. >> keep with us. that led to the eventual discovery of a romantic relationship between broadwell and general petraeus, and now general john allen is involved over his correspondence with the original woman, jill kelley. all sounds a little confusing, it is. let's get right to nbc's andrea mitchell who can help us sort it out. andrea, good morning to you. >> reporter: good morning.
